UnparsedText() |
| Modifier and Type | Method and Description |
|---|---|
Sequence |
call(XPathContext context,
Sequence[] arguments)
Evaluate the expression
|
void |
checkArguments(ExpressionVisitor visitor)
Method called during static type checking
|
int |
computeSpecialProperties()
Determine the special properties of this expression.
|
Item |
evaluateItem(XPathContext context)
This method handles evaluation of the function:
it returns a StringValue in the case of unparsed-text(), or a BooleanValue
in the case of unparsed-text-available().
|
Item |
evalUnparsedText(StringValue hrefVal,
String encoding,
XPathContext context) |
static URI |
getAbsoluteURI(String href,
String baseURI,
XPathContext context) |
String |
getExpressionBaseURI()
getExpressionBaseURI: this method returns the expression base URI
|
static XPathException |
handleIOError(URI absoluteURI,
IOException ioErr,
XPathContext context) |
static void |
main(String[] args) |
Expression |
preEvaluate(ExpressionVisitor visitor)
preEvaluate: this method suppresses compile-time evaluation by doing nothing
|
static CharSequence |
readFile(NameChecker checker,
Reader reader,
XPathContext context)
Read the contents of an unparsed text file
|
CharSequence |
readFile(String href,
String baseURI,
String encoding,
XPathContext context)
Supporting routine to load one external file given a URI (href) and a baseURI
